NFIB overexpression discriminated between metastatic versus non‐metastatic TNBC breast cancer patient‐derived xenograft (PDX) models (Fig 6A; Appendix Fig S7A) and NFIB, ERO1A and VEGFA were co‐overexpressed in these samples (Fig 6A and B). This evidence concerns the gene NFIB and breast carcinoma.
